I don’t think any regulations on companies advertising is good, because such regulations can harm the freedom of expression. And the right of free expression is one of the most important rights for all of us. We should be as careful as possible when we think of any regulations to such an important right. And it is much better to think of another way which is less harmful to the fundamental human rights. это звучит нормально?

This is very good and I understand it perfectly. Just a couple of small points:


I don’t think regulations on companies advertising is good because such regulations can harm freedom of expression. And the right of free expression is one of the most important rights for all of us. We should be as careful as possible when we think of any regulations and consider the impact on such an important right. It is much better to think of another way which is less harmful to fundamental human rights.

I would write the first sentence as:
I don’t think regulation on company advertising is good...

But the sentence you have is not wrong.
